Zephyr 141B is a Mixtral 8x22B fine-tune. Here are some interesting details

- Base model: Mixtral 8x22B, 8 experts, 141B total params, 35B activated params

- Fine-tuned with ORPO, a new alignment algorithm with no SFT step (hence much faster than DPO/PPO)

- Trained with 7K open data instances -> high-quality, synthetic, multi-turn

- Apache 2

Everything is open:

- Base Model: https://huggingface.co/mistral-community/Mixtral-8x22B-v0.1

- Fine-tune data: https://huggingface.co/datasets/argilla/distilabel-capybara-...

- Recipe/code to train the model: https://huggingface.co/datasets/argilla/distilabel-capybara-...

Have fun!

I like that they say how the model was trained for 1.3 hours on 4 nodes of 8 x H100s. By my rough calculation, that should probably have cost around $100 or so. (At $2 per hour, x 8 gpus x 4 nodes). Not free, but pretty cheap in the scheme of things. At least, once you know what you're doing.

What does ORPO stand for? Can't seem to find related links.

My current favorite “LLM breaker” below. GPT4, Claude, and this all fail.

Apples are better than bananas. Cherries are worse than apples. Are cherries better than bananas?

FWIW, Claude Opus (the paid model) gets the correct answer, and explains it well:

Based on the information provided, we cannot definitively determine whether cherries are better than bananas. The statements given only provide relative comparisons between apples and bananas, and apples and cherries, but do not directly compare cherries and bananas.

Here's what we know: 1. Apples are better than bananas. 2. Cherries are worse than apples.

However, these statements do not necessarily imply a transitive relation. In other words, just because A is better than B, and C is worse than A, it doesn't always mean that C is worse than B.

For example, if we assign numerical values to represent the quality of each fruit (higher numbers indicate better quality), we could have a scenario like this:

- Apples: 8 - Bananas: 6 - Cherries: 7

In this case, apples (8) are better than bananas (6), and cherries (7) are worse than apples (8), but cherries (7) are still better than bananas (6).

Therefore, more information would be needed to determine the relative quality of cherries compared to bananas.

To be fair, a lot of humans fail that. Including people that should know better.
